Sound Card

Sound Card

The sound card in a computer is an optional component. The computer is capable of running without a sound card but no sound will be available. Most computers come with an integrated sound card, meaning that the sound card is built-in to the motherboard. However for better sound quality, many people choose to purchase a separate sound card. The purpose of a sound card is to allow any sounds on the computer to be played via the speakers. A sound card converts the digital data (eg. a song) into sound waves you can actually hear, which are then output by the speakers. A sound card can also be used to record any audio using a microphone. The sample rate of sound cards is usually measured in kilohertz (KHz). The sample rate is the number of samples of audio carried per second, meaning the higher the sample rate, the better the sound quality will be. However the sound card is not beneficial if your speakers do not support same or better sound quality.
